Trek Fuel EX 9 Eagle 90 Lithium Grey: T-Type mechanics, no battery

With its 100% mechanical SRAM Eagle 90 T-Type drivetrain and 10-52 cassette, the Trek Fuel EX 9 Eagle 90 Gen 7 is aimed at riders who want a tough bike with no battery to charge.

Lithium Grey/Trek Black Splatter is a dark lithium grey scattered with black spatters.

Who is it for?

For the mountain biker who often rides far from anywhere and wants a drivetrain they can adjust themselves with an Allen key and a spare cable. Available from S to XL, this colourway also covers riders from 155 to 195 cm.

The LVR workshop view

Alpha aluminium, Trek's expertise. For the Gen 7 Fuel, Trek did not keep the new features for carbon alone: its most refined alloy, Alpha NEXT Platinum, gets the same modular platform. The rocker and lower shock mount can be swapped to change the geometry and end-stroke behaviour, and the ABP pivot on the rear axle helps the suspension stay active when you brake. Storage is hidden in the down tube.

	Alpha Silver	Alpha NEXT Platinum	OCLV Mountain
Level	Trek's entry-level alloy	The most refined of the Alpha alloys	Trek's mountain bike carbon
Construction	Alpha aluminium, hardtail frame	Alpha aluminium, adjustable Fuel platform	OCLV process tuned for impacts
Reference bike	Marlin 4 to 7	Fuel EX 5, 8 and 9	Fuel EX 9.8 and 9.9
What it means	Simple and affordable, no rear suspension	4.95 kg frameset in M, tough and more affordable	3.31 kg frameset in M, 1.64 kg less

Put simply: this Fuel EX 9 Eagle 90 puts the money into suspension, brakes and tyres rather than the frame. With equivalent suspension, the carbon of a Fuel EX 9.8 saves weight, not descending performance.

The T-Type principle mounts the derailleur directly on the rear axle, with no conventional hanger: it withstands knocks better and almost never goes out of adjustment after a crash. Eagle 90 uses the same system with a cable, which is cheaper to repair than an electronic derailleur.

On the technical climbs of the Espinouse, the 10-52 cassette and 30-tooth chainring let you keep a slow cadence without stalling. Shifting under load stays clean thanks to the T-Type sprocket design, even when you change gear at the wrong moment.

Which Fuel should you choose?

Model	Frame	Fork / rear	Drivetrain	Weight (M)
Fuel EX 8	Alpha NEXT Platinum alloy	Fox Rhythm 36, 150 / 145 mm	SRAM Eagle 70 1x12	16.58 kg
Fuel EX 9 Eagle 90	Alpha NEXT Platinum alloy	RockShox Lyrik Ultimate, 150 / 145 mm	SRAM Eagle 90 1x12	16.58 kg
Fuel EX 9 XT	Alpha NEXT Platinum alloy	Fox Factory 36, 150 / 145 mm	Shimano XT 1x12	17.14 kg
Fuel EX 9 X0 AXS	Alpha NEXT Platinum alloy	RockShox Lyrik Ultimate, 150 / 145 mm	SRAM X0 AXS T-Type 1x12	not disclosed

Our take: the Fuel EX 9 X0 AXS uses the same suspension with a wireless electronic drivetrain; its weight is not published. The Fuel EX 9 XT remains mechanical with Fox Factory suspension, for 17.14 kg in M.

LVR sizing advice

Between two sizes, we recommend the smaller one if you like playing with the terrain, the larger one if you want stability at high speed. The Line Dropper post goes from 150 mm in S to 200 mm in L and XL; the S rolls on a 27.5-inch rear wheel.

Size	S	M	L	XL
Rider height (cm)	155-165	165-177	177-188	188-195
Inseam (cm)	74-78	79-83	84-89	89-91
Dropper post (mm)	150	170	200	200
Wheels front / rear (in)	29 / 27.5	29 / 29	29 / 29	29 / 29
